IMPROVEMENT IN WINDOW-SCREENS.

Specification forming part of Letters Patent No. l 82.767, dated October3, 1876; application led C July 20, 1876.

.To all whom it may concern.-

Be it known that I, TIMOTHY NOWELL, of Indianapolis, county of Marion,and State of Indiana, have invented a new Improvement in ExtensionWindow and Door Screens, of which the following` is adescription,reference being had to the accompanying drawings.

The object of my invention 1s to construct a screen so as 4to make itadjustable to all widths of doors and windows, and, at the saine time,do away with cumbersome frames and the trouble of fitting, and to haveagood, substantial screen, that can be removed and replaced at will; andmy invention consists of two rollers provided with a pivot at one end,on which the roller may be revolved, Iand with a series of holes boredat different angles through the upper end, to receive screweyes to holdthe rollers in position on the window-frame. The two rollers are unitedby any kind of screen required, all arranged and adapted to be operatedas hereinafter more fully set forth and claimed.

Figure l represents a view ot' a window, attached to which is myimproved adjustable screen. Fig. 2 represents an edge view ofthe screenand rollers.

A A represent the window-frame; and the sill F is perforated with twoholes, g g, in'which the pivots at the lower end of the rollers B B'operate. On the rollers B B' are secured the screen or gauze Ein anydesired manner. The upper ends of the rollers B B' are perforated with aseries of holes, O C', bored at different angles, in which are insertedthe screw-eyes D D', as shown.

In setting up my improved screen, rst,

place one roller in position, and secure it to the sill F by means ofits pin g, and further secure the roller to the window-casing byscrew-eye D. Next, adjust the other roller with the proper width ofscreen uurolled, and secure it to the other side of the window-casing,as before described.

By this arrangement of adjustable screen I am enabled to fit all sizesof windows and doors, and do away with frames, Ste.; andthe screen canbe readily released at one side, and rolled up and secured to the otherside of the window or door, when required.

What I claim as new, and wish to secure by Letters Patent, is l l. Theroller B B', pivoted to the sill F at g, and provided with holes C C toreceive the screw-eyes D D', in the manner and for the purposes setforth and described.

2. In combination, the rollers B B', screen E, pins g, and screw-eyes DD', arranged and adapted to be used in windows or doors, as and for thepurposes specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

TIMOTHY NOWELL.
